Fans speculate Matty J cropped the winning Bachelorette out of his Instagram photo

Eagle-eyed fans of The Bachelor think Matty Johnson has something to hide...

On Sunday, the 30-year-old took to Instagram to post a sweet photo with his mother -- but many have speculated that the winner of Matty's heart, and the reality show, has been doctored out of the photo.

With his arm around the shoulder of his mum, the 30-year-old shared the touching moment as they stood before the picturesque Sydney harbour

"Sunday spend hanging out with my biggest fan" he wrote alongside the snap.

However, fans were quick to notice a detail about the photo, pointing out that someone to Matty's right had clearly been cropped out.

Commenters took to the post to theorise that the missing person on the left was likely Matty’s winning Bachelorette.

"His right arm is wrapped around Laura!" Wrote one fan.

"I bet his girl is on the other side," wrote another.

Many went a step further, assuming the identity of the cropped person to be Laura Byrne, this season’s front runner.

"Laura where are you girl?," wrote one commenter, while another suggested that "his arm is wrapped around Miss Laura!"

The 30-year-old jewellery designer -who many think bares a striking resemblance to Georgia Love - was the first to steal a kiss this season, and currently sits at the top of the Sportsbet leader board.

And if previous Bachelor seasons are anything to go by, the first kiss has proved to be a fast track to the final rose. Sam Wood and his now fiancée Snezana Markoski enjoyed a smooch on their first date, while Tim Robards also puckered up with his bride-to-be Anna Heinrich early on in their 2013 season.
